The “Java Decompiler project” aims to develop tools in order to decompile and analyze Java 5 “byte code” and the later versions. JD-GUI is a standalone graphical utility that displays Java source codes of “.class” files. You can browse the reconstructed source code with the JD-GUI for instant access to methods and fields.
The work of Java decompiler to convert .class file types into the Java source code. In simpler words, we can say that these decompilers help you to decompile the Java coding into readable form. This means you can also decompile APK files as an Android tool is programmed using Java.
These decompilers will assist you to analyze and investigate the code of Java classes say ArrayList, HashSet, and HashMap. So, if you are looking for some good and helping decompiler apps, then we have compiled a list of best decompilers for Java programs.

When a Java source code is compiled, it is converted into Java class file by the Java compiler with a .class extension. The class file contains highly optimized instructions in the form of Java instructions which is executed by the Java Virtual Machine or the JVM. .class file contains symbols with each bytecode instruction stored as one byte.
A Decompiler for Java has the capability to convert a .class file into Java source code. Although it may fail in giving the exact java source code, from which the .class file was generated, the majority of the code will be the same. A decompiler will be helpful in situations where you have lost the source code.
